Importantly ,we guarantee that our Sterling silver merchandise is 925 Sterling silver and Nickel-free. Our Marcasite comes primarily from Switzerland and from Thailand. Marcasite stones are individually hand set. When our Marcasite jewellery is created, we oxidize the silver to prevent future tarnish. This process gives all of our pieces the antique or vintage look. The eye-cathing Ruby Marcasite will makes you feel like a Hollywood glamour girl . Perfect for everyday and every occasion.
